My moonflowers, which are related to morning glories, sent out new branches when the tops snapped off this spring. I've never pruned morning glories, but there's a chance they will do the same. I would carefully straighten the bent stems, and not cut them unless the vines began to wither where they were bent. Sometimes a plant can rebuild a bent stem, but it takes time and must be treated gently, like a broken bone. Either way I don't know if they will bloom, because I don't know how they behave in your climate. The vines will definitely need something to climb, otherwise they will sprawl on the ground and likely get stepped on by imbeciles. Can you put a trellis in that spot? A teepee made from three or four long sticks tied together at the top? Make sure to sink the poles deep into the ground, at least a foot down, so it can't blow over in a strong wind. I've had that happen. I've also had wind and rain rip vines off of poles. You may want to gently tie the vines to whatever poles/supports you use, to prevent this. I hope this helps; blue morning glories are worth saving for their beauty alone, and it sounds like these have a special place in your heart.

Gardens require routine and regular gardening.

Please help! I got this plant about 10 days ago, started with just some brown spots and yellow leaves shedding. Now 1 shoot is dead and I would like to salvage the other two but not sure what to do next.

Were these planted into pots? Potted plants are difficult to evenly water and easy to over-water.
